iMPRovEMENT IN uMBRELLAs.

The Scnedule referred to in these Letters Patent and making part of thesame.

I, NICHOLAS STARR, of Homer, in the county ot' Cortland and State of NewYork, have invented certain Improvements in Umbrellas, of which thefollowing is a specication.

This invention has for its object to furnish a joint for the ribs offolding umbrellas which shall possess requisite strength and durability,and which may be furnished at a very small cost; and consists incert-ain speoic details of construction, which will be fully describedhereinafter.

In the drawing- Figure 1 represents a side elevation of the joint, withthe parts ofthe rib and the brace attached thereto;

Figure 2 represents a partial perspective'view oi the same;

Figure 3, an end elevation of the joint detached Figure 4, a partialsectional view; and

Figure 5, a plan v iew of the lmetal piece before itis formed to makethe joint.

To enable others skilled inthe art to make' and use my invention, I willnow proceed to describe fully its construction and method of operation.j

A represents a flat piece of metal, which is cut in any proper mannerinto substantially the shape shown in ng. 5.

By means of suitable formed pliers, or other instruments or means, thispiece of Vmetal is b ent at a a" a2 a, and to it are secured, by meansof rivets b b, the divisions of the rib and brace-rod.

The lower division of the rib is rigidly held in the closed socket a; ofthe joint, while the upper division is held in the open socket By meansof this construction the adjacent ends of the divisions oi the rib passby each other a certain distance, and they are each also clamped on thesides by the sockets,' as well as held by the rivets, so that they arebraced to resist lateral and downward strain.

A joint of great strength is thus-obtained which can,

be produced at a very small oost.

Having thus fully described my invention,

WhatA I claim as new, and desire to lsecure by Y
